| 摘 要： | 综合运用岩心分析、测井、生产测试等静态和动态资料，从多层次、多角度逐级揭示了平方王油田沙四中滩坝沉积特点。从层内非均质、层间非均质、平面非均质这三类储层的宏观非均质性入手，探讨了滩坝相低渗透油藏储层宏观非均质性的地质特征及其对水驱油开发和剩余油形成、分布的控制作用。研究表明，层间非均质和层内非均质主要控制了油层的水淹层厚度及垂向的剩余油分布；平面非均质和层内非均质主要控制了油层的水淹面积和平面剩余油分布。

| Abstract: | eterogeneity and residual oil distribution of the reservoirs with beach bar facies and low permeability were gradually revealed from many levels and aspects by means of the data of core analysis, logging and production test. According to the characteristics of beach bar sedimentation in Pingfangwang oil field, the heterogeneities of intrabed, interbed and planar in the reservoirs were discussed. The effects of heterogeneity on residual oil formation and distribution were studied. The interbed and intrabed heterogeneities mainly control the flooding thickness and vertical residual oil distribution, and the planar and intrabed heterogeneities mainly control the flooding area and interbed residual oil distribution. |
